  • WIFI development board,4M bytes.5V 1A switching power supply (switching power supply）onboard.

How to get it started in for Arduino:

- Setup driver

Before you use mini D1 boards, you need set up CH340g driver.

- Python

On Windows you need install Python 2.7.10.

On Linux & MAC OSX, you don't need install it, comes preinstalled with OS.

- Installing Hardware package "Boards Manager or GIT".

We recommend using GIT, you can always get the latest version.

Getting setup in for Arduino IDE:

0. You will need a link to copy and paste, but I can't link it here. Search Google for "arduino ide esp8266 board manager" -- the first result should be for a "readthedocs" website, and that should have all the instructions you need. However, for clarity I will list them here as well.

1. Ensure you have Python installed (this might be optional -- I haven't installed Python directly, but I installed the for Arduino IDE and had no issues).

2. Open the for Arduino IDE and go to File --> Preferences

3. Under "Additional Board Manager URLs" at the bottom, paste the link (it's to a JSON file) you copied from the other page into that box and hit "OK"

4. Go to Tools --> Board --> and select Board Manager (near the top)

5. Search for "ESP8266" and install the result (should be from "ESP8266 Community")

Selecting the board for your sketch:

1. Go to Tools --> Board and select either “LOLIN(WEMOS) D1 R2 & mini” or "NodeMCU 1.0 (12-E Module)" — either of these worked for me

2. Be sure to select which COM port the board from Tools -> Port

3. Check that the upload rate is 115200 (it should already be)

Test the board with "Blink":

1. Go to File --> Examples --> ESP8266 and select "Blink" at the top

2. You shouldn't need to change anything, so click Upload

3. Once it's finished, check that your blue led light is blinking

Test the board's WiFi with for "Arduino OTA":

0. This isn't necessary, but to be sure your WiFi module actually works you need to try connecting

1. Go to File --> Examples -->for Arduino OTA and select "BasicOTA"

2. Only changes you have to make are on lines 7 and 8 for your WiFi SSID and password

3. (Optional) Save the sketch

4. Go to Tools --> Port: If all was successful, you should be able to see the ESP8266 board here (COM whatever) -- select it

5. Hit upload and open the serial monitor

6. Once the program is finished uploading, make sure to change the baud rate to 115200 on the serial monitor

7. Check to make sure you get the "Ready" message, followed by an IP address

      Received the product in a few days with each chip packaged in anti static bags. A nice added bonus is the extra I/O pins that can be soldered based on your application. For a little over $3 ea, I think this is the most versatile of the 8266 chips. I’m just getting started back into electronics (I’m 70) and these are so easy to apply into IOT projects with a huge support community. I was able to put together a temp humid web server in a matter of a couple hours. Highly recommend this seller as he also reached out to me after the sale to insure all was ok, and an email address if I should have questions. I’ve received no free products or incentive to write this review.

      This works fine! I was worried that the tools setup would be a chore, but just go to the ESP8266 project on GitHub, which tells you where to put in a board manager link in the Arduino IDE, and then select the WeMos R2 & Mini board in the setup menu, and you're good to go!

      If you're not already familiar with programming at the C level in general, and/or Arduino-type programming, getting started on this particular board will probably be rough, though -- it's not as "easy on-ramp" for beginners as the plain Arduino, or the Teensy series, but that's not what I was looking for, so that's fine.

      Two things to watch out for:

      1) The pinout in the pictures of this listing are FROM THE UNDERSIDE of the board. If you solder on the connectors as if that was the overside, you'll end up with a board whose pins are mirrored from what all tutorials and symbols on the web expect.

      2) You'll probably want to double-clock the CPU to 160 MHz; there's an option for this in the board setup menu. This wasn't clear in most of the setup instructions, but it works better, connects faster, can do HTTPS / SSL better, and so on, with that option turned on.

      Beware that it draws up to 200 milliamps from the 3.3V rail when actually connected and transmitting, so if you want to battery power it, you need a big battery or some way to only occasionally turn this on (or both.)

      Most of these work great, however, one of the five arrived non-functional. The ones that did arrive worked great for some simple ESPHome projects in Home Assistant. These don't have bluetooth, since only the ESP32s have that, but if you don't need it and you just need a little microcontroller for a project here and there, I absolutely recommend it for that.

      Some arduino products (based on NINA wifi) simply don't work reliably. This seems to work perfectly.

      Note: this isn't the board's fault, but the Arduino IDE takes some setup to talk to these, and the latest version (3.1.0) of the board manager package does not work. You get an incomprehensible error message about time_ns and things fail to compile. Drop back to 3.0.2 and all is well. This sort of thing isn't atypical with Arduino projects, which seems to be very much the wild west in terms of software,

      Editing and adding two stars. The last batch I got performed flawlessly with MicroPython 1.19 firmware.

      These are wonderful and cheap little 8266 boards, but the CH340G USB to UART bridge really drags them down. Can't get the thing to flash? Try a different USB cable. Got garbage characters on your serial output? Try a different USB cable. Yeah, really. The USB cable can make a difference. I don't know if it's the CH340G or the CH340G driver for Windows, but something is not quite right. My experience using the same USB cables with NodeMCU and Adafruit Huzzah32 (and their CP2102 USB to UART bridges) is stable and working consistently. These were a great price, but not worth the headaches. Stick with a CP2102 equipped device.

      I love these chips. They are very useful and I have used them for a few things now and though they don't have a ton of memory and their processing speed is lower than things like the ESP32, I still prefer them for certain applications.

      Built a few WiFi enabled thermometers with these.

      They sit in various rooms of my house and sense the temperature and I can hit a little webpage I coded into the device to see what the temperature is where they are located. So basically, they are acting as remotely readable temp/humidity sensors.

      Also, I used these to build a controllable outlet where I can log into a webpage on it over the network and control the on/off state of an outlet. Then I modified the code so it would reach out to the remote thermometers I mentioned to get the temp and turn on/off the outlet based on the temp.

      This way they control a heater in my shed to keep the temperature stable through the winter. It has been working great!

      From what I understand, these are clones of the Wemos D1 boards. I purchased these to read various sensors and setup remote control of some fans. They are trivial to configure and program, with Arduino sketches readily available. I programmed them from a Linux Mint laptop with the device connected directly to the USB interface.

      One programmed, I soldered on the provided headers and attached to the board.

      I supplied power via 9V battery and a voltage regulator circuit. You can also use a breadboard power supply or, if your power requirements are small, directly from the USB. Keep in mind that some sensors may be sensitive to voltage differences.

      No other issues to speak of. It connected to WiFi without issue.
